Elite stingrays aren't bad, neither are sponge filters, and you can get a HOB filter and buy a strainer so the fry can't get sucked up. The last is my favorite, works like a charm and you get great filteration.
Not necesarily especialy in a 10 gallon tank and you can put stuff at the output to stop it. Part of it the holes are too large in a intake filter. I just bought the bag for aquaclear filters sold separately, cut it to fit my filter and rubberbanded it on and it worked great. Some filters you can adjust the flow, though the main reason is the holes are too big.
